for inspecting, repairing and cleaning. As will be seen by inspecting Fig. 1,,my novel 7 Other objects of this invention will be apparent ventilator is composed of S shaped, elongated, as the specification of the same proceeds. sheet metal units'26 which'are set in parallelism' In the drawings forming a part of this speciwith one another, each such unit being composed 30 fication and accompanying the same: of an outer plate 21, an inner plate 28, a bridge Fig. 1. is a fragmentary, sectional, perspective or cross plate 29, connecting the respective upper view showing my novel ventilator passages as and lower edges of the outer and inner plates 21 applied to an ordinary window. and 28,'and two opposingly turned flanges 3|] and Fig. 2 is a front elevation 'of the ,structure 3! at the upper and lower ends of said 8 shaped forming such passages, portions of the same being unit 26. The outer and inner plates 21 and 28 are broken away; preferably vertical in position, while the cross Fig. 3 isa diagram illustratingv the application plate 29 and the upper flange 30 are inclined in of such passages to an automobile hood; downward and outward directions, and the lower 40 Fig. 4 illustrates in a diagrammatic manner flange 3| is inclined in a downward and inward 40 the combination of my novel air passage strucdirection, in relation to the window sash .22, but it ture with hinged shutter vanes, while 1 being understood that the ventilator units 26 are Fig. 5'is a fragmentary, sectional, perspective on the outside of the window and its sash 22. view showing my novel air passages in cornbina- A plurality of such 8 shaped units 26 are pro- 4 tion with a hinged box-like air deflector placed vided on the outside of the window, the topmost in front thereof; of them terminating in an upward flange 32' Fig. 6 is a diagram showing such a deflector having a resilient yielding sealing means 33 inwith hinged auxiliary vanes thereon; corporated thereon, being preferably in the form -Fig. ,7 is a semi-diagrammatic fragmentary of a strip of rubber and engaging the sash 22 section showing an independent closed ventilator sealing the same in all of its positions but per- 50 unit embodying my invention and being adapted mitting its upward or downward movements, as to be removed or replaced in an efficient and easy will be understood, and as has been more fully manner. v explained in my co-pending application. The Fig. 8 is a partly sectional front elevation showlowermost unit 26a of my ventilator structure,

ing my invention applied to a ventilator unit preferably 'endswith its cross plate 29a and is 55 continued in an outwardly directed flange 34 which lays on and may be secured to the window sill 20.

The individual 8 shaped units 26 of my device may be secured at their ends engaging the two window frames 2| by any suitable means, as will be understood by those versed in this art, and as also has been explained more in detail in my co-pending application in Connection with the ventilators there shown.

It will be seen that my S'shaped sheet metal units with their cross plates and their overlapping fianges will provide 8 shaped elongated passages generally indicated by the numeral 35 for the air from the outside to the inside of the window, as shown by the arrows 38, and that the air current will be dampened, made gentle, and

highly diffused by the plurality of such passages provided by my device and that the dirt, dust, water, snow, etc. in said air current, or reaching my ventilator units in any other manner, will be prevented from entering the inside of the building, but will be deposited on the cross plates and flanges in my device and will ultimately be caused to slide or move outwardly and downwardly on the cross plates 29. It will be understood that the flanges 30 and 31 may be made to overlap each other to a desired degree.

Finally, I preferably provide an increasingly larger passage along the arrows 36, as has been explained hereinbefore, by making the distances between the lower edges of the flanges 3| and the bridge plates 29 thereunder, then between the free edges of the flanges 30 and 3|, and finally between each upper flange 30 and the bridge plate 29 thereabove, respectively, larger and larger. The air pressed from the outside to the inside, as .by a catch device on a moving vehicle, will thereby be forced upwardly and inwardly, depositing its foreign matter on the plates and in the corners forming traps, and the speed of the air will be gradually lessened so that it will be delivered to the inside in a gentle highly diffused manner.

In Fig. 2 a front elevation of a plurality of S shaped units 26 proper is shown, portions of the structure being broken away since the height of the S shaped elements and their parts is usually small as compared to the usual length of such a ventilator and it is indicated in said Fig. 2 that the units 26 are secured together in a left hand and right hand end systems of the device generally indicated by the numerals 31 and 38, the outer ends of said two systems being secured together and being received in a movable manner in heads secured at the two sides of a window frame so that the whole device may be lengthened or shortened in a telescopical manner to the width of the window in question, as has been more fully explained in my co-pending application, and will be understood by those versed in this art. The inner termination of the right hand system of the two telescopic units is indicated by the numeral 31a, while the similar termination of the left hand units is indicated by the numeral 38a.

In Fig. 4 my s shaped ventilator units are shown as built across an opening 43 in a wall of the device to be ventilated, like an automobile, and a plurality of vanes 44 is provided in combination therewith in the inside of the device to be ventilated, said vanes 44 being hinged as at 45 and being interconnected by a hinged link 46, the upward or downward movement of which will cause said vanes to open or close and thereby permit a desired degree of ventilation and air current, as will be understood. My experience has been that my 5 shaped air passages in combination with such hinged shutter vanes will provide an exceptionally gentle and easily regulatable ventilation for an automobile or other device or building.

In Fig. 5 a unit 41 of my novel 8 shaped air passages is shown combined with an inclined single outer deflector or vane 48 having upper and lower sealing sides 49 and 50.

This form of my device as most of the other ones, is particularly designed for automobiles and the one shown in Fig. 5 may be built anywhere into the wall of the body of the automobile, like over the door, the broader side or opening 5| of the box formed by the plates 48, 49 and 50 being turned. in the direction of the motion of the automobile thereby catching and forcing the air into said box, the air afterwards entering through the passages of the member 41 into the interior of the car. It will be seen that broadly speaking, my device, like the one described in connection with Fig. 4 and like many of the later ones, and like some of them shown in my earlier mentioned co-pending application, is composed of two main units, one being designed to guide the air to a second'unit which is to diffuse and lead the air into the space to be ventilated, the first one may be generally called the air guide of my device, and the second one the diffusing and resistance member of my device, the first one in the embodiment of Fig. 5 being represented by the inclined plate 48 and its associated parts, while the second one is represented by the S shaped passages 41.

In Fig. 6 I diagrammatically illustrate a further improvement on the same basic idea of my device having novel catch and guide means for the air which lead the air to a so called resistance device and force it therethrough, the whole procedure resulting in a gentle, diffused, clean stream of air.

In the device of Fig. 6, the diffusing or resistance member is indicated at 52 and preferably may embody therein'the S shaped passages described hereinbefore, while the air catch and guide is in the form of an inclined plate 53, the open side of the same being preferably turned in the direction of the motion of the car or other vehicle, as indicated by arrow 5341, so that a large volume of air will be forced underneath said large single catch or guide vane 53. Inthis modification said vane further shows additional similar vanes or deflectors 54 in an inclined po-' sition secured on its inner side, said deflectors 54 distributing, guiding and forcing the air through the resistance and diffusing device 52. Both the main guide vane 53 and the smaller deflectors or vanes 54 on the inside thereof may be made stationary and secured in favorable inclined positions, or they may have pivots at their secured edges, as indicated at 55 and 56, respectively.

It is also preferred toprovide spring means around the pivots 56 having the tendency to allow the vanes 54 to be forced backwards towards the main inclined plate 53 according to the pressure of the inrushing air. Finally, the vanes 54 obviously will be made narrower and narrower as they approach the pivot 55 of the main plate 53.

In Fig.7, a removable ventilator is shown, generally indicated by the numeral 51, being in the form of an elongated box open to the outside at one of its long sides, as at 58, wh'ile the other opposite similar side 59 turned towards the inof the s shaped passages described hereinbefore,

v embodied therein. The box shaped ventilator has a closedtop BI and closed bottom 62, and the two lateral ends of it are also closed, fitting comparatively tightly into the opening '63 in the wall of the device to be ventilated.- Spring means 64 and 65 may be secured to the top andthe bottom of said opening 63, and when the box 51 is pushed between them, the same is. kept-there in a se-" cured and sealed, but still resilient and removable manner. It is obvious that this device .will

guide the air into theinterior in ,the manner described hereinbefore, while the dirt, moisture,

and air will be deposited-in the S shaped'pasl co-pending application." The grille 69 is prefer sages and then shed outwardly. In case of need, 1 the whole device may easily be removed from between the springs 64 and 65, inspected, cleaned With equal facility.

' In Figs. 8 to 10 I show anotherembodiment of or repaired and thensnapped back into its place my improved ventilator, which generally follows the lines of some of the embodiments described. in my earlier applicationmenti'oned a bove,and

l is composed of acentral box 66 having the, open ends 61 and 60, closed top and bottom, an open front closed -bythe grille work 69, and an open rearor'inner side I0. The boxis housedintw o heads '"II and I2 which show fiangeslland in 1 this} embodiment screw means are employed to secure the whole device in its place like over the door, or window of an automobile-through the openings I4 in the manner obvious from the drawings, and described :in-ful1 detailin my said ably inclined, as shown, providing a box which is narrower at one end and wider at the other, and said box shows the mentioned resistance and diffusing member I5 embodied adjacent to its inner open side I0, being composed of the S shaped plate units-and passages described hereinbefore, In front, of said resistance unit 15, a pluralityof hinged guide-vanes or deflectors I6 are provided 'hingedly secured in the top 11- and bottom 18 of the box 66','as at-"I9 and 80 Each vane 16 may-carry a-pirrBI at. its lower end whereby it is hingedly secured into a link rod 82. vanes having a screw-threaded pin 64 projecting downwardly therefrom and playing ina curved, I

slot 85 in the bottom 18. ,It is, obvious thatby this mechanism the vanes I6 may be set to any.

desired angle or inclination in relation to the unit I5, and in certain inclinedjpositionthereof they will guide and force the air through said unit into the inside of the vehicle, while in the opposite positions of the same, they will act to exhaustthe air from the inside. Vanes I6 are preferably made with increasing widths towards the wider end of the box 66, and if the car is moving in the direction of the decreasing vanes 16, arrow 86, each succeeding vane will have a chance to catch some of the air and guide it to the unit I5. 7

The preferred form of the vanes I6 is shown in the sectional diagramof Fig. 11, and as there indicated-the outer end 90 is wider than the inner end 9| and the two sides'92 and 93 are formed with curved outlines connecting said ends, one of said curves being concave, as, at 92, and the other being convex, as at 93, the concave surface, according to my experience, acting a's'a thereinto.

An'arm 83 may be secured to one of said wardly movable system or box 40 engaging a respectiveelement 4| belowthe wind-shield of the automobile and being movably sealed thereagainst by rubber sealing means 42- so asto pm:-

vide more or less ventilation for the space at the drivers seat according to the degree the box 40" is raised or lowered, the airbeing introduced as indicated by arrows 40a. v

In Figs. 12 and 13 Ishow a diagrammatic plan and cross-sectional'elevation of the combination ofav guide unit and resistance unit for my ventilator.

The ventilator is a'box-like structure I00, closed on all sides except theinner side I 0 I opening into the automobile or other object to be ventilated.

Said openside IIIIhas built thereacross a resistance and difiusing unit I02 which may be of any construction, but preferably'showing the S shaped bafiies and passages described hereinbefore. The projecting part I03 of the box I00 may have openings I04 inits bottom and top parts having pivoted vanes I05 inserted therein which may beset at an inclination'to the respective side of-theboxand so catch the air and guidev it into said box'and to the resistance unit I02, as

,willbe obvious from the earlier explanations and from inspectingthe diagram of Fig. 12. By setting said vanes with a reverse inclination to the side of the box, thesame T. will act as suction means, for drawing the air from the inside of the automobile instead of guiding the outside air In the diagram of Fig. 13, additional vanes I06 are indicated in appropriate openings in the vertical front side I0'I of, the box I00, said additional vanes I06 being omitted from the showing in Fig. 12 or being completely closed and their action being identical to those of the top and bottom vanes I05. v

In Fig. 14 I show a sliding regulator applied to my bafiie system in asecti0nal diagram. In this diagram the numeral 26 again represents the system: of S shaped baffles and passages as de-' having open portions- I22 and closed parts. I23

: infhorizontal alternatingsections, as, will be understood. f The regulator I is shown in the dia- I gram as fully open and in case-the same is pushed upwardly as indicated by the arrow I24, its closed portion I23 will gradually reduce the free area a of the entrance to the passages I25 between the baflles in the system 26 and so reduce the air admitted through the same until finally said passages may be entirely closed.

I also want to again refer to the form of my de- I vice shown in Figs. 1 and 2 and remark that in some cases the baflle system, there shown and described in the specification, mayconvenlently be suspended instead of being secured only at the bottom thereof. In such cases appropriate screws with enlarged heads are provided in'a suitable stationary object above the ventilator and a; slot 34a may be provided-at each end of.the,bafl le system 25 and in. the .top thereof, as shown in Fig. 1, said slot 34a having a larger circular portion and a narrower elongated part pointing oppositely from the two ends towards the center of v the ventilator, When itis desired to suspend the ventilator the same will be telescopically extended to the right length, then the two circular larger portions of the slots 34a will be passed over the heads of the screws provided for the suspension of the ventilator, whereupon the same will be further extended, the stems of the screws entering into the narrow portion of the slots 34a so that the ventilator will be prevented from freeing itself of the screws on account of the large heads thereof engaging the margins of said narrow slots. In one word, my ventilator with the added slots 34a in its top will be adapted to be suspended I through a bayonet locking action when telescopically extended.

In practice, I have found that the form of my invention, illustrated in the drawings and referred to in the above description, as the preferred embodiment, is the most efficient and practical; yet realizing that the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the fact that various changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of my invention, as set forth and defined in the appended claims.

What I claim as new, is:

1. In a ventilator, a first plurality of outer plates substantially in registering position but spaced apart from one another, a second plurality of similar spaced apart registering individual inner plates; cross plates connecting pairs of ad- 7 jacent individual plates in said two pluralities, and an inwardly turned lateral extension plate at each free end of each inner and outer plate in each of said pairs, said extension reaching to a part of the distance between said outer and inner plates, the respective inner and outer plates in each of said pairs, being in staggered relation to one anof said system, having vanes at its side turned towards said system of passages, said vanes being inclined to said deflector plate, said deflector plate being adjustable as to its inclination.

4. In a ventilator, a system of openings and air passages, and an inclined deflector plate in front of said system, having vanes at its side turned towards said system of passages, said vanes being inclined to said deflector plate, and said vanes being adjustable as'to their inclination to said deflector plate.

5. In a ventilator, a means to provide system of openings and air passages, and an inclined deflector plate in front of said system, having vanes at its side turned towards said system of passages, said vanes being inclined to said deflector plate, said vanes being adjustable as to their inclination to said deflector plate, and yielding automatic means to normally open said vanes but allow their closing on said inclined plate upon an increase of the air pressure on them.

6. In a ventilator, a column of a plurality of superposed angular generally S-shaped members, each member being composed of an outer plate,

an inner plate, a bridge plate connecting the low-' er end of the inner plate with the upper end of the respective outer plate, an upper flange plate projecting towards the center of the column from the upper end of the inner plate, a lower flange plate projecting towards the center of the column from the lower end of the outer plate, said bridge plates and said upper flange plates forming identical acute angles with the center plane of said column, and said lower flange plates forming identical acute angles with said center plane, the

inclination of said lower flange plates to said center plane being opposite to the inclination of said upper flange plates and said bridge plates in relation to said center plane, the adjacent bridge plates, flange plates and the free ends of said flange plates being spaced apart from one another and from the respective adjacent plates, thereby forming a plurality of tortuous but free passages for the air between the interlocking neighboring portions of said members.

7. In a ventilator as set forth in claim 6, the free ends of said upper flange plates being bent double upon said plates and being spaced apart therefrom.
